Ted Kennedy Diagnosed With Malignant Brain Tumor

Sen. Ted Kennedy has been diagnosed with a malignant brain tumor and will remain hospitalized for at least several days as he and his family determine his treatment options.

The Massachusetts Democrat suffered a seizure Saturday and has since been hospitalized at Massachusetts General Hospital in Boston. He has been talking and joking with family and friends while undergoing a battery of tests that revealed the malignant tumor, a glioma in the left parietal lobe, according to the hospital.

"He has had no further seizures, remains in good overall condition and is up and walking around the hospital," Drs. Lee Schwamm and Larry Ronan said in a joint statement released by the hospital.

"The usual course of treatment includes combinations of various forms of radiation and chemotherapy," they said. "Decisions regarding the best course of treatment for Sen. Kennedy will be determined after further testing and analysis."

Kennedy, the second-longest serving senator in U.S. history, has represented Massachusetts in the Senate since 1962.

Obama talked with Vicki Kennedy, the senator's wife, Saturday and said he was more optimistic after that converstion.

"The news came in today and it's a lot worse, but he's a fighter. He's been fighting on behalf of working families all his life. … It's a testament to how beloved he is that you are seeing well wishes from across the aisle from everyone in political life and Massachusetts."

In a statement released to the press, Sen. Hillary Clinton, D-N.Y., in Kentucky for an election night rally, said, "Ted Kennedy's courage and resolve are unmatched, and they have made him one of the greatest legislators in Senate history. Our thoughts are with him and Vicki and we are praying for a quick and full recovery."
